Ram usage when audio device has been removed

[Firenz]

Greetings, as I already mentioned in title, ts3 client is raising it's ram usage with about 500K/s. I have plugged 3 sound cards to my PC and it's set to a particular card, which I just disabled in W7 settings as usual. When I turned back on this sound card, ram usage has disappeared in a second or two. I doubt if it's important in this case, but client is set to playback and capture on Creative Sound Blaster Audigy SE, another sound card is integrated with my motherboard (realtek) and last one is hdmi.
I forgot to add: latest client version 64bit, W7 Ultimate.

If you go to Services (you can search for it) can you see something like Nvidia ForceWare ?

Nope, I have nvidia display driver service, nvidia stereoscopic 3d driver service and nvidia update service daemon.
